This is not a cave, it is a grotto, it is Fern Grotto. In speleology, the science about caves, caves are of natural origin, and grottos are artificial, shallow, and covered by kitschy rocks, minerals and shells. So if we should choose, we would also call it a grotto.
Fern Grotto is a major tourist draw on the island Kauai. It is located at Wailua River, right in the middle of the east coast. To reach it, the visitor board a ship and are carried 15 minutes upstream to a pier. From here its five minutes pleasant stroll to the grotto. The first impression is a sort of amphitheatre, with steep, green walls. We guess the cave is a river cave formed in a soft layer of lava by the river. An overhanging cliff which works pretty well as a natural shelter. The tropic climate and the regular rains allow an abundant plant growth, which makes this place pretty comfortable.
However, the sight is at least partly artificial as a plantation-created reservoir above the cave caused a steady flow of water. This water supply allowed the growth of ferns on the ceiling of the cave. But the closing of the sugar plantations has ended the water supply. This change and damages caused by two recent hurricanes required a refurbishing of the cave by the Hawaii Tourism Authority and Kauai County at the cost of $440,000.
However, as an attraction this cliff cave is much too boring, so the management invented the whole entertainment stuff to make the visit more impressive. The boat ride, hula music during the ride, marriages in the grotto, more music at the cave, smiling people everywhere. Pretty creepy. If you are not afraid of such things, go to Fern Grotto and enjoy.
